Abstract: This study investigated maintaining hydration with H2O, or a carbohydrate-electrolyte solution (CES) compared to mild dehydration by 1.5 – 2.0 % body mass (NF), on game-simulated hockey skills involving a decision-making component. During a 90-min scrimmage, rate of perceived exertion was significantly higher in NF during the 2nd period compared to CES and during the last half of the 3rd period compared to H2O. During testing, CES and H2O had a faster average time during the weave agility test, a smaller increase in time between trials for reactive start skating sprint, and higher target hit percentage during the reactive passing and randomized shooting tests compared to NF. CES and H2O scored significantly better than NF during 5 of 8 hockey fatigue questionnaire responses, and all 4 subsections of the Profile of Mood States questionnaire. The results indicate that proper hydration can decrease perception of fatigue and help increase on-ice skill execution.
